Text retrieval from Firebase is not displaying in app

I am working on a messaging app and I want to display the location where a message was sent from under the message content. I try to do this by sending the user's location data to Firebase, and then attempting to retrieve the data to display it as a string.

Getting the users location works fine (I am using

CoreLocation

to do so) as does uploading data to my Firebase realtime database. I save the location along with each message as such:

I wasn't able to do the retrieval any other way. Instead I exploited JSQMessagesViewControllers other built in methods to solve my problem. The framework has a built in variable called senderDisplayName. Since the nature of this app I am making is anonymous I didn't need to use it, so I manipulated the senderDisplay name to display the user's location instead.
